English is a West Germanic language originating in England, and the first language for most people in Australia, Canada, the Commonwealth Caribbean, Ireland, New Zealand, the United Kingdom and the United States of America (also commonly known as the Anglosphere). It is used extensively as a second language and as an official language throughout the world, especially in Commonwealth countries and in many international organisations.

Modern English is sometimes described as the new global lingua franca.  English is the dominant international language in communications, science, business, aviation, entertainment, radio and diplomacy.  The influence of the British Empire is the primary reason for the initial spread of the language far beyond the British Isles.  Following World War II, the growing economic and cultural influence of the United States has significantly accelerated the adoption of English.

A working knowledge of English is required in certain fields, professions, and occupations. As a result over a billion people speak English at least at a basic level.  English is also one of six official languages of the United Nations.

English is the language most often studied as a foreign language in the European Union (by 89% of schoolchildren), followed by French (32%), German (18%), and Spanish (8%).  [Source: English Language at  Wikipedia]
